The JBL Charge 4 comes with 6 different buttons. Each of the buttons has a different purpose. You can also combine two buttons to enter different modes.

We have explained what each button does, and we have also included a list of combinations that you can use on your JBL Charge 4 speaker.

JBL Charge 4 Buttons Explained

Unlike other JBL speakers, the Charge 4 comes with all the buttons in one row. The JBL Charge 4 has 6 different buttons. Here’s what they are and their purpose:

Power Button

The power button is located in the middle, next to the Bluetooth button. The power button is used to turn on/off the speaker.

If the speaker is off, press the power button 1 time to turn it on. When the speaker is ON, the power button will have a steady white light.

If you want to turn the speaker off, press the power button one time and the speaker will turn off. The power button will be dark when the speaker is off.

Bluetooth Button

The Bluetooth button is located in the middle, next to the power button, The Bluetooth button is used to put the JBL Charge 4 into pairing mode.

When the speaker is powered on, press the Bluetooth button 1 time to put the speaker into pairing mode. When the speaker is on pairing mode, it can be discovered by other Bluetooth devices and you can pair both devices together.

The Bluetooth button will have a steady white light when in paired mode. To exit the discovery mode, press the Bluetooth button one time. If that doesn’t work, you can turn off the speaker to exit discovery mode.

Play Button

The Play button is located on the right side of the speaker (or left side if you have it upside down), next to the Volume Up (+) button. This button is called the “Play/Pause” button because it also pauses the music.

If you have the speaker paired with another device and the music isn’t playing, press the Play button one time to start the music. If the music is playing, press the Play button one time to pause the music.

This button won’t mute the music, it will pause it. So, you won’t miss anything. Once you press the Play button (to resume the music), the music will start where you left it.

If the music is playing, press the Play button 2 times to skip a few seconds of the music.

Volume Buttons

Thee are two volume buttons, the volume up and the volume down button. The volume up button is shaped as a plus (+), while the volume down is shaped as a minus (-).

The buttons are used to increase and decrease the volume output of the speaker. When the music is playing, press the Volume Up (+) button to increase the volume. You need to hold the buttons for a few seconds to increase the volume to the maximum. If you want to increase the volume just a bit, then press the Volume Up (+) just one time.

The Volume Down (-) is used to decrease the volume output of the speaker. To mute the music, you need to press and hold the Volume Down (-) button for a few seconds. To decrease the volume just a bit, press the button one time.

Note: These two buttons don’t have any purpose if the speaker isn’t playing music. If the speaker isn’t playing music, you can only use these buttons for combinations that we will explain later in this article.

Connect Plus Button

Next to the Volume Down (-) is the Connect Plus button. This button activates the Connect Plus feature that allows two or more JBL Speakers to pair with each other and play the same music.

Once the speaker is turned on and the music is playing, press the Connect Plus button one time to activate it. Next, activate the Connect Plus feature on all other devices you want to pair. After a few seconds of activating, the music will start playing simultaneously on all the speakers.

Note: Only speakers with the Connect + feature can connect together. If your other speakers have Connect or PartyBoost then you can’t connect them together.

Battery Indicator

At the bottom of the JBL Charge 4 speaker, you will see 5 small lights. These lights indicate how much battery the speaker has. If all 5 small LED lights have a white steady light it means that the speaker is fully charged.

Each of these LED lights indicates a 20% of charge. So, if 3 LED’s have a white light it means the speaker has 60% battery, and so on. These lights won’t be always visible, you need to press any of the buttons (except the power button) to activate them.

JBL Charge 4 Ports

On the back of the JBL Charge 4, there’s a small flip door. Once you open the door, you will see 3 ports.  1x USB-C port, 1x USB-A port, 1x AUX port.

The USB-C port is used to charge the speaker. Simply put the charger that the speaker came with into the USB-C port, then put the other end of the charger into a wall charger and start charging your speaker.

The USB-A port is used to charge other devices. The JBL Charge 4 speaker comes with lithium batteries, these batteries can be used to charge other devices as well.

You can use the AUX port to pair the speaker with another device using an aux cable.

JBL Charge 4 Button Combinations

The JBL Charge 4 has only 6 buttons, but you can combine these buttons to do different things. Here are the combinations you can use:

Reset The JBL Charge 4

To reset the JBL Charge 4 you need to press and hold the Volume Up (+) and the Bluetooth button at the same time for a few seconds. Once the speaker turns off, you can release the buttons and turn on the speaker again.

You should reset the JBL Charge 4 when the speaker is having software problems. The factory reset will return the speaker into its default mode. The reset will remove any previously connected devices and remove any sound modes or settings you choose before. You will have to manually choose and connect to devices again.

Low-Frequency Mode

By default, the JBL Charge 4 has enough bass on its sound. But, if you want to increase the bass then you should put the speaker into Low-frequency mode.

To put the speaker into low-frequency mode, press and hold the Volume Down (-) and the Bluetooth buttons at the same time until the oval ring has a steady white light.

If you want to exit low-frequency mode, press and hold the Volume Down (-) and the Bluetooth buttons at the same time until the oval ring doesn’t have white light around it.

However, we don’t recommend using this mode as it can damage the woofer of your speaker. If you decide to use it, make sure to use a volume of 50-60% and not higher.

Service/Lock Mode

Service mode isn’t a mode you want to put your speaker. However, you can accidentally put the speaker into service mode, and exiting it is harder.

You can put the speaker into service mode by pressing and holding the Bluetooth and Play buttons at the same time. Once in service mode, none of the buttons will work. The speaker won’t turn on unless connected to a power source.

To exit the service mode, plug the charger into the speaker and press and hold the same buttons (Bluetooth and Play) for a few seconds until the speaker turns on. Next, remove the charger and the speaker will work normally.

If the speaker is already turned on and into service mode, then connect the speaker with a charger and hold the same buttons (Bluetooth and Play) until the speaker turns off. Next, turn on the speaker by pressing the power button.

Firmware Version

If you want to know the firmware version of the JBL Charge 4, press the JBL Connect + and Volume Down (-) buttons at the same time. The speaker will play a pre-recorded sound that tells you the exact version of the speaker firmware.
